Also known as Dom 2b, `Punta S'Argiola'. Cyclopygid Bed
Where: Sardinia, Italy (30.3° N, 8.7° E: paleocoordinates 74.0° S, 114.3° E)
• coordinate estimated from map
• small collection-level geographic resolution
When: Amorphognathus ordovicicus conodont zone, Punta S'Argiola Member (Domusnovas Formation), Kralodvorian (449.8 - 445.2 Ma)
• BA 5/6 Foliomena community. Listed as upper Kralodvorian; Domusnovas overlies Portixeddu Formation.
• formation-level stratigraphic resolution
Environment/lithology: offshore shelf; lithified, shelly/skeletal, calcareous mudstone
Size classes: macrofossils, mesofossils
Collection methods: BA 5/6 Foliomena community; Member occurs in five outcrops, but is only .89 to 1.5 meters thick, (on average 1.1 m). All the photographed specimens come from these two locations (only approx. 15 km apart) and so I will consider this a pooled sample, despite more than one location.
